Add MapInsertOrReplace<>() to insert a key-value pair into a map if the
key is not already present, or replace the existing value for key if the
key is present. The original value can optionally be returned to the
caller in this case.
Map insertions now use either MapInsertOrReplace<>() or
std::map<>::insert() directly.
Use MapInsertOrReplace<>() when the map should be updated to contain a
mapping from a key to a value regardless of whether the key is already
present.
Use std::map<>::insert() to insert a mapping from a key to a value
without replacing any existing mapping from a key, if present. If it is
important to know whether an existing mapping from a key was present,
use the returned std::pair<>.second. If it is important to know the
existing value, use the returned std::pair<>.first->second.
This change has a slight positive impact on performance.

This makes it easier for clients to start the Crashpad handler, instead
of requiring them to know how to construct arguments for the handler
themselves. Note in the TEST that -a is no longer required.

The handler is now capable of uploading crash reports from the database.
At present, only one upload attempt is made, and the report will be
moved to “completed” in the database after the attempt, regardless of
whether it succeeded or failed.
The handler also has support to push annotations from its command line
into the process annotations map of each crash report it writes. This is
intended to set basic information about each crash report, such as the
product ID and version. Each potentially crashy process can’t be relied
on to maintain this information on their own.
With this change, Crashpad is now 100% capable of running a handler that
maintains a database and uploads crash reports to a Breakpad-type server
such that Breakpad properly interprets the reports. This is all possible
from the command line.

Upload isn’t actually hooked up yet, but this establishes the upload
thread and provides all of the plumbing to process pending reports. For
the time being, SkipReportUpload() is called for all pending reports.

crashpad_handler is Crashpad’s exception handler server.
Currently, it runs a loop to receive exceptions, and exits when it no
longer has any clients. In the future, this will be extended to write
and potentially upload dumps.
The handler is expected to be started by its initial client via the
CrashpadClient interface.
